Aphids are a diverse group of small insects that feed on the nutrient-rich sap flowing through plants. They can also be an annoying garden pest! You and your friend created two community gardens in your neighbourhood, and you visit the sites to see if your gardens are now host to these pesky insects. Bad news: you find hundreds of individuals representing several species of aphids crawling around on your plants. You and your friend tediously count and identify these aphids.
1. Which community would have the greatest Shannon Diversity Index value? Briefly justify your choice [Note: Do not calculate the H' value, but simply base your decision on the patterns seen in the graphs below]
2. Foxglove aphids and green peach aphids are two species that consume a very broad range of plant species. Despite their diverse diet, you notice that Site A is host to foxglove aphids but no green peach aphids. Similarly, Site B is host to green peach aphids but no foxglove aphids. Your friend suggests these species do not coexist due to competitive exclusion. Can we definitively say this? Provide one argument in support of this hypothesis and one against.
